The FT-IR and FT-Raman spectra of p-hydroxy-N-(p-methoxy benzylidene) aniline have been recorded in the region 4000-400 cm and 3500-100 cm, respectively. The optimized molecular geometry, vibrational frequencies in ground state have been calculated using density functional B3LYP methods (DFT) with 6-31+G(d,p) and 6-311++G(d,p) basis sets. The observed FT-IR and FT-Raman vibrational frequencies ...
